There
are a number of technologies that utilize or generate magnetic
fields in various areas such as medicine, industry, research and
so forth. On the other hand, precision equipment easy to be affected
by magnetic fields is widely used. As such equipment is improved
in precision, it becomes more susceptible to the noise of magnetic
field,
In accordance with customer requirements, Ohtama designs and builds
a shield room for equipment that generates magnetic fields and for
equipment susceptible to the noise of magnetic fields.

Panel
structure type room

Permalloy panels are mounted onto base panels, and assemble
the shield room as a prefab house structure.

On-site assembling
type room

Magnetic shield material and components are assembled into
a magnetic shield room, which is to be supported by the walls
and ceiling of a room.

Magnetic
shield case

To protect a high-magnification electron microscope from external
disturbing magnetic fields, this case is manufactured and installed
as a shield case to cover the electron microscope completely.

High-precision
air-conditioning unit

Installing an air-conditioning unit in a magnetic shield room
makes it possible to precisely control the temperature, humidity
and cleanliness of the room.
